Former Leith Harbour Commissioners tug photographed in Leith in March 1976. She was built locally at the Henry Robb yard in 1958.
In 1981 she became PULWELL LIMA and then went to Canadian owners as BEAUFORT SPIRIT. After a chequered career she was broken up in 2004 in Canada.
I see an excellent shot of her on the site as BEAUFORT SPIRIT.
